• A. Amount of oxygen evolved increases as the availability of carbon dioxide increases.
• B. Amount of oxygen evolved decreases as the availability of carbon dioxide increases.
• C. Amount of oxygen evolved increases as carbon dioxide in Water is absorbed by sodium bicarbonate.
• D. Amount of oxygen evolved decreases as carbon dioxide in water is absorbed by sodium bicarbonate.
